Occasionally, it is necessary to consider in a model that some beams only lie loosely on top of one another without screwing or welding. In RFEM 5, you can easily meet this condition with a Nodal Release. For this, you need to define a release with the desired release condition on the relevant node in the Nodal Release dialog box. The example shown in Image corresponds to this with a shear force release with a property of being fixed and Vz positive. With a lifting load follows the decoupling of both members as a result.
